mnesnnrne Application filed June 24,

This invention relates to measuring apparatus, and has for one of its objects to provide a novel, simple and highly eflicient apparatus of this character through the medium of which the length of cables, well casings and other'pipes and the like, and the depth at which an oil or other wellboring tool is working maybe readilyascen tained.

, With the foregoing and the other objects in View, the nature otwhich will become apparent as the description proceeds, the invention consists of the construction, combination and arrangen'ient of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, wherein: I

Figure 1 is an elevational view illustratingv the manner in which the apparatus is adapted to be used for indicating the length of a Well pipe or casing,

Figure 2 is a detail view on an enlarged scale of the measuring apparatus,

Figure 3 is a horizontal sectional View taken on the plane indicated by the line. 3-8 of Figure 2,

Figure 41 is a vertical sectional view taken on the plane indicated by the line ;1- 1 of Figure 3,

Figure 5 is a horizontal sectional view taken on the plane indicated by the line of Figure 2, and

Figure (5 is a vertical sectional view taken on the plane indicated by the line 66 of Figure 2. r

Corresponding and like parts'are referred to in the following description, and designated in the several views of the accompanying drawings, by similar reference cha acters.

In. the drawings, 1 designates the rotor of a well known type of oil well drilling machines, and 2 the pipe or casing which is lowered into the well as the drilling thereof advances.

The measuring apparatus, which in the illustrated application. thereof, is adapted to indicate the depth of the well at any stage of the drilling thereof and is adapted to be operated by and during the lowering of the pipe or casing 2 into the well, comprlses a register 3 which in the preferred embodi- Inent thereof consists of a casing 1, a main shalt 5, and counter-shafts 6, 7, 8 and 9. The shafts 59 are provided with disks 9, respectively, which bear numbers APPARATUS.

192a Serial No. 118,286.

vlsible through openings 5 9 respectively,.in the casing 1. The numerals of the disk 5 register inches, those of the disk 6* register feet, those of thedisk 7* register feet in units of tens, those of the disk S feet in units of a hundred and those of the disk 9 feet in units of a thousand. The shafts 5-9 are connected by gears 10 which are of such construction that a revolution of the disk 5 will impart one-tweltth of a revolution to the disk 6, and so on throughout the series 01 disks.

'lhere'gister 3 is supported upon the rotor 1 for movement radially with respect thereto, and the supporting means thcrelorpret erably comprises a plate or platform 11 upon which it isslidably mounted, anda post 12 by which the plate is secured to the. rotor. The register 3 is provided with guides 13 which are received by grooves 1 1 provided on the plate or platform 11; This connection between the register 3 and plate or platform 11 prevents the former from having any lateral movement with respect to the latter.

The register 3 is operated by the pipe or casing 2 through the medium ofa concave roller 15 and a sprocket chain 16 of which the latter engages a sprocketwheel 17 fixed to the former and asprocket wheel .18 fixed to "the shaft- 5. The roller 15 is. supported by a bracket 19 which is secured. as at :20 to the register 8' and is provided with a forked portion 19. embracing the pipe or casing The roller 15 fits within the forkedportion 19 of the bracket 19, and the arms of saidbracket portion are provided with bayonet slots'itl tor the reception of the ends. of the axle 15 of the roller. said slots permitting the roller to be readily applied to or removed from the bracket. The arms of the bracket portion 19 are provided with slots 21 which open out throu h their free ends. A concave roller 2a is also mounted within the bracket portion 19, and the axle 22 of this roller is journaled at its ends in the slots 21. The rollers 15 and contact with the pipe or casing 2 at diametrically opposite sides thereof, and are maintained in contact with the pipe or casing by springs 1 3 which are secured as at 21 to the arms of the bracket portion. 19 and detachably connected with the ends of the roller axle 22. llhe free ends of the springs 23 are provided with loops 25 to permit these parts to be detachably connected. to the roller axle 22*. As the slots 21 open out through the free ends of the arms of the bracket portion 19 and as the springs 23 are detachably connected to the axle 22. of the roller 22, this roller may be readily applied to or removed from the bracket 19.

From the foregoing description, taken in connection with the accompanying drawings, it should be apparent that to install the apparatus it is only necessary to remove the roller 22 from the bracket 19, secure the plate or platform 11 to the rotor 1, mount the register upon the plate or platform in a manner to position the "forked portion 19 of the bracket 19 in embracing relation with the pipe or casing 2, then apply the roller to the bracket, and thereafter connect the springs 23 to the axle 22" of this roller. As the register 3 is supported by the plate or platform 11 for radial movement with respect to the rotor 1, and as the roller 22 is supported by the bracket 19 for radial movement with respect to the rotor, this roller anc the springs 23 may function to hold the roller in such frictional contact with the pipe or casing 2 as to insure the positive operation of the register by and while the pipe or casing is being lowered into or raised out of the well. Furthermore, as the register 3 is supported for radial movement with respect to the rotor 1 it is impossible for the former to be injured by the lateral movement of the pipe or casing 2.

It should be understood that the drawings are merely illustrative and do not pretend to give exact proportions. Furthermore, the said drawings are illustrative of a preferred construction, it being our expectation that various changes and modifications may be made without departing from the spirit and scope of our invention.

What is claimed is 1. A measuring apparatus of the character set forth, comprising, in combination with a rotor, a pipe or casing passing through the rotor, a register, means supporting the register for radial movement with respect to the rotor, a roller contacting with and adapted to be rotated by the pipe or cars ing, means for holding the roller in contact -with the pipe or casing, and means connecting the roller to the register to permit the movement of the roller to operate the register.

2. A measuring apparatus of the character set forth, comprising, in combination 'ith a rotor and a pipe or casing passing therethrough, a register, means supporting the register for radial movement with regrooves and carried by the second member in radial relation to the first member, a register slidably mounted on the plate for movement radially with respect to the first member and provided with guides fitting in the grooves, a bracket carried by the register and provided with a forked portion embracing the first member, a roller ior operating the register and journaled'on the forked portion between the first member and register and contacting with the first member, a second roller rotatably and adjustably supported in the forked portion and removable therefrom and contacting with the first member at a point diametrically opposed to the point of contact between the first member and said first roller, and springs connected to the bracket and second roller and urging it in the direction of the'first roller.

In testimony whereof we afiix our signatures.
